Which policy during the Cold War aimed at preventing the spread of communism, often associated with the early Cold War era?

• A. Containment
• B. Colony
• C. Cuban Missile Crisis
• D. Credit

Answer: (A)

Containment is the policy being tested. It became the guiding approach in the early Cold War to stop communism from spreading to other countries. The idea, sparked by diplomat George Kennan and put into practice through actions like the Truman Doctrine, the Marshall Plan, and Western security alliances, was to keep Soviet influence from expanding by supporting free nations economically, politically, and militarily. It focuses on preventing new countries from becoming communist rather than promoting reforms elsewhere. The other terms don’t fit: a colony is a political status, not a policy; the Cuban Missile Crisis was a specific crisis event, not a broad doctrine; and credit has no relevance to Cold War geopolitics.
